In light of the current International Association for the Study of Pain (IASP) clinical practice guidelines (CPGs) and the European Society for Medical Oncology (ESMO) guidelines, the topic of cannabinoids in relation to pain remains controversial, with insufficient research presently available. Cannabinoids are an attractive pain management option due to their synergistic effects when administered with opioids, thereby also limiting the extent of respiratory depression. On their own, however, cannabinoids have been shown to have the potential to relieve specific subtypes of chronic pain in adults, although controversies remain. Among these subtypes are neuropathic, musculoskeletal, cancer, and geriatric pain. Another interesting feature is their effectiveness in chemotherapy-induced peripheral neuropathy (CIPN). Analgesic benefits are hypothesized to extend to HIV-associated neuropathic pain, as well as to lower back pain in the elderly. The aim of this article is to provide an up-to-date review of the existing preclinical as well as clinical studies, along with relevant systematic reviews addressing the roles of various types of cannabinoids in neuropathic pain settings. The impact of cannabinoids in chronic cancer pain and in non-cancer conditions, such as multiple sclerosis and headaches, are all discussed, as well as novel techniques of administration and relevant mechanisms of action.

Objectives: To evaluate how often pain is assessed and treated in pediatric trauma patients transported by Emergency Medical Services (EMS) to a pediatric emergency department (ED), and to compare current practice with national recommendations of the Polish Ministry of Health for prehospital pediatric pain management. Methods: We conducted a retrospective analysis of EMS and ED documentation for all trauma patients under 18 years of age transported to the Pediatric Teaching Hospital of the University Clinical Center of the Medical University of Warsaw between 1 January and 31 December 2021. A total of 981 patients with injury or suspected injury or burns were included without exclusion criteria. For patients with documented pain scores, we analyzed pain intensity (0–10), the scales used [Visual Analog Scale (VAS), Numerical Rating Scale (NRS), Wong–Baker Faces Pain Rating Scale (FACES)], body region injured, Glasgow Coma Scale (GCS) score, suspected alcohol or psychoactive substance use, and type and route of analgesic administration. We further evaluated non-pharmacological interventions, pain reassessment, and achievement of at least 50% pain reduction, as defined in national guidelines. Statistical analysis included Student’s t-test or ANOVA for quantitative variables and maximum likelihood chi-square tests for qualitative variables (α = 0.05). Results: Pain was assessed in 839/981 (85.5%) patients; 651/839 (77.6%) reported pain, most frequently of moderate intensity. Despite this, only 208/981 (21.2%) patients received analgesics prehospitally. Morphine and paracetamol were the most frequently used drugs, predominantly administered intravenously, while non-opioid monotherapy was commonly used in patients with lower baseline pain scores. Less than half of all patients received any non-pharmacological intervention whatsoever. Pain was reassessed in 734/839 (87.5%) patients, with a mean reassessment time of approximately 10 min; however, in many cases reassessment occurred earlier than the expected onset of analgesic action. Overall, only 29.4% of patients with pain and documented reassessment achieved the recommended ≥50% reduction in pain intensity, and at least 70.2% of the cohort had no documented evidence of treatment fully complying with national recommendations. Conclusions: In this real-world prehospital and ED cohort, pediatric trauma pain remains under-treated, and adherence to national guidelines on opioid-based analgesia and pain reassessment is suboptimal. Further efforts are needed to improve documentation, expand the recommended pharmacological options for mild pain, and strengthen education on guideline-concordant pediatric pain management in EMS.
